Pin bushings & hone to fit.....$40.00
Polish crank...................$25.00
Check Rods.....................$16.00
Balance........................$125.00
Deck block.....................$60.00

Total..........................$386.00

Add in the rebuild kit, cover, headbolts, cam, RV head, from EB...approx $900.00. Plus all the little extras that add up: bolts, RTV, hoses, carb rebuild, tools, fluids, ect, ect...

I've got a drawer full of receipts that Im scared to add up lol. Some can do it cheaper I'm sure, really just depends on how thorough you wanna be...
